New glow wire test requirements (650 °C) for parts close to contacts

, K. L; z+ \) ^6 s& u7 {9 X$ lDecision approved by the 44th CTL meeting 2007
Question:
Due to the new requirements of 60947-1:2004, parts close to contacts are subject to glow wire test performed at temperature of 650 °C. Is a glow wire test necessary for the green part (figure 1) or isn’t a glow wire test required for this part?
Decision:
  W, ~& N# W7 r0 P  G& k3 D  r) mAlthough the green part (figure 1) of this switch is mechanically separated from the contact element, the glow wire test should be done with 650 °C. During normal operation, the switching element and the contact element are mounted together. Due to this fact and the relatively large amount of material, a test should be done.
